Whats the evidence? Please quote.
There are hundreds, if not thousands, of religions.
Most of them come with moral frameworks / imperatives / duties / whatever you wish to call it.
At best, only one of them is what it claims to be (ie: coming from gods and/or accurate descriptions of gods/the supernatural). All others then must be human inventions.
We know for absolute fact that humans invent religions. We've literally observed it happening.
So we actually have demonstrable and observed precedents of humans doing this.
But we have no such demonstrable precedents of gods or angeles or whatnot doing this.
Since all religions tend to make the same type of claims, the most likely outcome is that all are human inventions.
I could invoke Occam's razor as well here.
There's no need to assume supernatural entities as the source of any religion, because we already have a perfectly decent candidate
which has already been observed to invent religions: humans.
I could go on for quite a while in more detail. But imho, the above is already more then enough to support my statement that religions (and therefor also the moral values contained therein) are of human origin.
